Find Your Air Solution

Not every air quality problem needs an air purifier. Answer 4 questions and get the right solution type — plus relevant guides and matching products from our canonical data.

Direct Answer

Indoor air quality problems fall into six solution categories: portable air purifier, HVAC filtration upgrade, source control, ventilation, humidity/moisture management, or a combination. The right answer depends on what pollutant you're dealing with — not every problem is solved by buying a filter.

Important: Carbon monoxide, radon, and active mold require source correction first. An air purifier is not a substitute for CO detection, radon mitigation, or moisture remediation.

How this tool works: Recommendations are based on deterministic logic using canonical product data from AHAM-verified CADR figures, ENERGY STAR database records, and manufacturer specifications. No AI inference. Source-control overrides (CO, radon, mold, CO₂) are hard-coded safety rules per EPA and ASHRAE guidance. Product specs pulled from /data/products/ canonical JSON — missing fields are labeled "not verified" rather than assumed.
